7965 flashes screen and hangs on green light on boot
I've googled but not been able to find anyone else having this problem. We have about six 7965 phones that won't boot up. When I plug them in the screen flashes white briefly and the headphone light comes on for a fraction of a second before the green speaker light comes on and hangs there with the screen completely blank. I've tried both holding hash to try and flash a new firmware and booting with the phone off the hook to boot a backup image but nothing works; I just get the same result.
Can anyone tell me what this indicates? These phones are all out of support now and no one seems to mind if we just chuck them but it would at least be nice to know if I can take a couple home, fix them myself, and add them to the lab.
Thanks for the reply Carlo. I'm not too sure how to check that stuff but we have about 300 phones, all of which are working correctly. We've also set up some new phones lately which needed the firmware changing on them and these have all worked correctly as well as a few rebuilds I had to perform by using the thing where you hold the hash button down. I expect this would confirm that the DHCP and TFTP are working correctly, would it not? I've been doing all of this from exactly the same switch port.
I have had two 7965's this morning do the same thing. I tried to do a factory reset with no luck. Personally I don't think it is a firmware issue as we have many other 7965's working fine. Potentially the firmware on the individual phone has become corrupted, that is why I tried to do a factory reset. Disconnect phone, then reconnect it and hold down the # key with no luck. Speaker indicator stays lit and the screen is blank. I have encountered several issues with the 7965 model phone that appears to be hardware related. Just wanted to throw out what I have been seeing. If anybody has a resolution to this issue, I would love to hear it.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
